My subscribers are getting this tip today...There are 250 cases of 100% varietal Tempranillo being released by Clos Du Bois as we speak. It's non-vintage, because to have a commercial lot they had to put 95&96 together. It's $30 with all proceeds going to charity, and it's a special bottling dedicated to long time winery employee (she goes back to the Frank Woods days), Inez Ferrari. There will be greater quantity in coming years.

It's really tasty...structure not unlike a Merlot...flavors of berries, plums and wild violets. I score it 90/84

I've had Pagor's Petite Sirah and have only seen their Tempranillo at Wine Club Santa Clara. The Petite was noteworthy for supposedly having been aged in old whiskey barrels; it sucked. Wine Club wanted around $8 for the Tempranillo.
I think Pagor is a Santa-barbara-area winery, as the Petite carried a SB designation. Also, the only other place I've seen them is "The Tasting Room" in Los Olivos. Don't have their phone number, but I'm sure if you call the Tasting Room they will have it, or info about the winery. FWIW, Charlie doesn't have Pagor in his newest edition either.
Hope this helps.

Castoro Cellars has been making a Tempranillo for a few years now. I've been getting it through their wine club, so I don't really know if they make it in commercial quantities. I haven't tried it for about six months, but I think I remember it as a nice, smooth easy to drink wine, pretty close to the description you give for the Clos du Bois. Not a world beater, but a very drinkable wine.

I should have waited until I got home before I opened my big mouth. I have before me a Castoro Cellars 1996 Tempranillo. However, it is a Wine Club Selection. It was made in very limited quantities only for the wine club. Therefore, I suspect they don't have a commercial offering like Clos Du Bois. So, how do I get some of the Clos Du Bois Tempranillo? Who do I call.

Re the Clos Du Bois Tempranillo...call the winery tasting room at (707) 857-1651...if they give you any trouble or stall...let me know and I'll intercede. I was promised that the wine would truly be available...otherwise I would not have reviewed it.
